The first season of Adventure Time, an American animated television series created by Pendleton Ward, premiered on Cartoon Network on April 5, 2010, and concluded on September 27, 2010, and was produced by Frederator Studios and Cartoon Network Studios. The series is based on a short produced for Frederator's Nicktoons Network animation incubator series Random! Cartoons. The season follows the adventures of Finn, a human boy, and his best friend and adoptive brother Jake, a dog with magical powers to change shape and size at will. Finn and Jake live in the post-apocalyptic Land of Ooo, where they interact with the other main characters of the show: Princess Bubblegum, The Ice King, Marceline the Vampire Queen, Lumpy Space Princess, and BMO.
After the original short became a viral hit on the internet, Cartoon Network picked it up for a full-length series that previewed on March 11, 2010, and officially premiered on April 5, 2010. The season was storyboarded and written by Adam Muto, Elizabeth Ito, Pendleton Ward, Sean Jimenez, Patrick McHale, Luther McLaurin, Kent Osborne, Pete Browngardt, Niki Yang, Armen Mirzaian, J. G. Quintel, Cole Sanchez, Tom Herpich, Bert Youn, and Ako Castuera.
The first episodes of the season, "Slumber Party Panic" and "Trouble in Lumpy Space" were watched by 2.5 million viewers; this marked a dramatic increase in viewers watching Cartoon Network when compared to the previous year. The season ended with the finale "Gut Grinder" on September 27, 2010. Soon after airing, the show began to receive critical acclaim as well as a large fan following. In 2010, the Adventure Time episode "My Two Favorite People" was nominated for a Primetime Emmy Award for Outstanding Short-format Animated Program, although the series did not win. Several compilation DVDs that contained episodes from the season were released after the season finished airing. On July 10, 2012, the full season was released on Region 1 DVD; a Blu-ray edition was released on June 4, 2013.
